Invidia 15+ Subaru WRX/STI Single N1 Titanium Tip Cat-back Exhaust

• 304 stainless steel construction
• Reduces back pressure and turbo lag
• Increases throttle response and horsepower
• Improves performance and weight reduction
• Enhances exhaust sound
• Single N1 Titanium Tip design

Invidia exhausts are engineered to optimize performance while enhancing the aesthetics and sound of your vehicle. Crafted from durable 304 stainless steel, these systems prioritize weight reduction without compromising strength. The Invidia 15+ Subaru WRX/STI Single N1 Titanium Tip Cat-back Exhaust is designed to decrease back pressure and turbo lag, resulting in improved throttle response and increased horsepower.

As one of the recommended initial modifications for car enthusiasts, replacing your OEM catback with this Invidia system offers a trifecta of benefits: increased horsepower, enhanced style, and an improved exhaust note. Invidia's team of engineers conducts thorough research and development for each exhaust component, ensuring optimal performance tailored to customer needs.

The exhaust design strikes a careful balance between back pressure and exhaust gas velocity, maximizing performance gains across the power band. This attention to detail sets Invidia apart, delivering a quality exhaust system that goes beyond simple aesthetics to provide tangible performance improvements.

but the point is

it's not as simple as just strap on a drain pipe and gains for days. A "quality" exhaust system maximizes performance gains by design.

Far more engineering goes in to the design of an exhaust system than many realise. From a performance perspective, there is a fine balance between exhaust back pressure and exhaust gas velocity. Too large a diameter pipe, and low down power and torque is sacrificed (particularly on naturally aspirated cars), too small a diameter or added restrictions and bottlenecks in the system, and the engine is unable to push gasses out of the combustion chamber efficiently, reducing power and torque. There are many other technical aspects such as 'scavenging effect' which are beyond the scope of this document
